i have found that the problem come from the sound, because if i unchec the box enable in the sound part of the launcher the game worki think is a wrong parameter in the computer sound but i don't know what i need to change because the game worked with the sound before and i change nothing in the sound

i always launch the game in admin mod and in xp sp3the anti-aliasing box was already uncheckbut i know that the problem come from the sound but i don't know what i need to doi can play but only when i uncheck the enable box in the sound tab

I am not running it in XP SP3 compatible mode. I have Windows 10. Still I don't believe it has to with your sound settings. It is a administrator rights issue. Look at the properties of all the .EXE files in the directory and match up all their properties. They will all have to be the same. Especially the ones starting with URU.

Then, I have it installed in "C:\GAMES\Deep Island\" and not in the standard Progam Files directory of Windows.
